Novel chemical conversion of eggshell to hydroxyapatite powder
Hydroxyapatite (HA) which compose around 70 % of our bone is an example of bioactive ceramics most commonly used in bone implantation. Because of their excellent bioactivities, hydroxyapatites are regarded as attractive biomedical materials. In this work we have succeeded in producing hydroxyapatite...
